You cannot trust social media to keep your private data safe: Story of a Twitter vulnerability

I‘m always worried about the private information I have online. Maybe this is because I have been hacking for a long time, and I know everything can be hacked. This makes me a bit paranoid. I have never trusted web sites to keep my private information safe, and nowadays it is impossible to not have private information published on the web, such as a social media web site. Sooner or later you could get hacked, this is a fact.   Currently, many web and mobile applications give users the option…

Impressions from Black Hat, Defcon, BSidesLV and IOAsis

A week has passed since the Las Vegas craziness and we’ve had some time to write down our impressions about the Black Hat, Defcon and BSidesLV conferences as well as our own IOAsis event. It was great for me to meet lots of people—some of who I only see once a year in Las Vegas. I think this is one of the great things about these events: being able to talk for at least a couple of minutes with colleagues and friends you don’t see regularly (the Vegas craziness doesn’t…

The Value of Data

Have you ever entered an office and seen a pile of money sitting unattended and easily accessible on a desk? How many people in your company have a key or combination to a safe with money inside and can open that safe without any controls? Do you leave money in a non-secure place that everyone knows about and can freely access? Your probable answer to all these questions is NO, which makes sense—what doesn’t make sense is how so many companies don’t think the same way about data….

Hackito Ergo Sum: Not Just Another Conference

My name is Jonathan Brossard, but you may know me under the nic Endrazine. Or maybe as the CEO of Toucan System.. Nevermind: I’m a hacker. Probably like yourself, if you’re reading this blog post. Along with my friends Matthieu Suiche and Philippe Langlois,—with the invaluable help of a large community worldwide—we’re trying to build a conference like no other: Hackito Ergo Sum. First, a bit of background on conferences as I have discovered them: I remember really well the first conference I attended almost a…

Atmel AT90SC3232CS Smartcard Destruction

Having heard that Atmel actually produced three variants of the AT90SC3232 device, we did some digging and found some of this previously never-seen-by-Flylogic AT90SC3232CS.  We had already several AT90SC3232 and AT90SC3232C.  We assumed that the CS was just a 3232C with an extra IO pad.  Well, one should never ass-u-me anything!  The AT90SC3232CS is a completely new design based on the larger AT90SC6464C device. Decapsulation revealed that Atmel actually did place an active shielding over the surface of the device.  A 350nm, 4 metal process was used on the AT90SC3232CS…

A free Windows Vulnerability for the NSA

Some months ago at Black Hat USA 2011 I presented this interesting issue in the workshop “Easy and Quick Vulnerability Hunting in Windows,” and now I’m sharing it with all people a more detailed explanation in this blog post. In Windows 7 or Windows 2008, in the folder C:WindowsInstaller there are many installer files (from already installed applications) with what appear to be random names. When run, some of these installer files (like Microsoft Office Publisher MUI (English) 2007) will automatically elevate privileges and try to install when…

Windows Vulnerability Paradox

For those who read just the first few lines, this is not a critical vulnerability. It is low impact but interesting, so keep reading.   This post describes the Windows vulnerability I showed during my Black Hat USA 2011 workshop “Easy and Quick Vulnerability Hunting in Windows”.   The Windows security update for Visual C++ 2005 SP1 Redistributable Package (MS11-025) is a security patch for a binary planting vulnerability. This kind of vulnerability occurs when someone opens or executes a file and this file (or the application used to…
